ThinWire Ethernet is used in any size environment. It is ideal for a small

stand-alone network in which personal computer and workstation users

share resources, such as prmters and storage devices.

ThmWire

works

well as a small- to medium-sized stand-alone

local

area

network

(LAN)

in a small business or in a department of a larger organization where

personal

computer

and

workstation

users

need

local

resource

sharing

and

powerful

computing

resources.

LAN

isa high-speed

communications

network that covers a limited geographical area, such as a section of a

building, an entire building, or a

cluster

of buildings.

Unshielded

Ethernet

The

Unshielded

Twisted-Pair

Ethernet

Adapter

delivers

megabits-per-

performance

to the

desktop,

work

area,

and

system

over unshielded twisted-pair building cable.

Unshielded tvdsted-pair adapters connect a

•Personal computer with DEPCA, DELUA, or DELQA Ethernet controllers

to the Ethernet network by means of the

DIGITAL

ThinWire Ethernet

Multiport Repeater

(DEMPR).

Small stand-alone local area networks, where a

personal

computer

and

workstation

usershare

limited

local

resources

(printers,

storage

devices),

can be connected as a subnetwork to large local area and

wide

area

networks.

Functionally, the

office

adapter and wiring

closet/SER

adapter work as a

pair to match the 50-ohm impedance on a ThinWire Ethernet coaxial cable

to the impedance on an unshielded twisted-pair cable. Thus, unshielded

tv«sted-pair building wiring can be used, in addition to ThinWire cable, to

run Ethernet to the desktop.

Unshielded Twisted-PairEthernet Adapters are compatiblewith the ThinWire

Ethernet products and
